Boundary-layer combustion has been shown to be effective for reducing viscous drag in hypersonic flow. However, the implementation of boundary-layer combustion in realistic scramjet configurations can be affected by non-uniform flow entering the combustor. Experimental results showing the effects of flow non-uniformities on boundary-layer combustion will be presented.
